Works but gets warm
The board functions as expected, but it does get somewhat warm during prolonged Wi-Fi transmission. Make sure to provide adequate ventilation in your enclosure.

Stable performance
I have been running this board for weeks without any crashes. The dual-core processor handles multitasking nicely. Highly recommended for embedded projects.

Good value but docs could be better
Hardware quality is great for the price. I deducted one star because the pinout diagram in the manual was slightly unclear. Otherwise, it performs well.

Great for prototyping
I love using this for rapid prototyping. The USB upload speed is fast and the community support for ESP32 is huge. No issues so far.
Q: Does it support Bluetooth Low Energy?
A: Yes, the ESP32 chip supports both classic Bluetooth and Bluetooth Low Energy (BLE) protocols.
Q: What is the maximum current output on the 3.3V pin?
A: The onboard regulator can supply approximately 600mA to the 3.3V pin, but we recommend drawing less for stability.
Q: Is this compatible with the Arduino IDE?
A: Yes, this board is fully compatible with the Arduino IDE. You can install the ESP32 board manager package to start programming.
Q: Can I power this with a LiPo battery?
A: Yes, you can connect a 3.7V LiPo battery to the VIN and GND pins, provided the voltage stays within the acceptable input range.
Q: Does it have a physical Ethernet RJ45 port?
A: This model supports Ethernet connectivity via SPI interface. It does not have a built-in RJ45 port unless specified in the variant description.
